1979 Gmc high sierra pick up

This is a rare GMC high Sierra pick up. It has 40k original miles; however, it has a recent rebuilt engine from Colorado engines (all papwork available). It spent most of its life in a barn in Colorado, and the last 6 years in Southern California. The truck has never seen salt. It’s a perfectly running strong work truck, or definitely worthy of a restoration. The winch works. It’s been well maintained.
